Description

The present invention relates to a method for producing a packaging container filled with a liquid product in addition to milk, juice, alcoholic beverages, mineral water, green tea, and the like, and to the packaging container.

Flexible paper packaging laminates have been used for many years to package liquid products as well as liquid foods. A packaging container 20 such as that shown in FIG. 6 for milk, juice, sake, shochu, mineral water and other beverages, for example, is creased in a fibrous base material (eg, paper, etc.) / Plastic laminate. The web-like packaging laminate material is formed into a tube shape by the longitudinal seal in the longitudinal direction, the filling material is filled into the packaging material formed in the tube shape, the tube-like packaging material is laterally sealed in the transverse direction, and cushioned. Shaped or pillow-shaped package (primary shape container) 13.

Panels 21a and 21b that form side walls as shown in FIG. 7 by cutting the pillow-shaped package 13 into one container at the horizontal seal portion and folding it into a fold or a valley along the fold line. From a packaging material such as a vertical seal portion 22, a fin horizontal seal portion 23, a panel 24 forming a top wall, a flap (folded piece generated when forming a top wall or a bottom portion) 25, etc. The container 20 is formed.

For gable-top (roof-type) paper packaging containers, cut the paper packaging material into a predetermined shape, obtain blanks sealed in the container vertical direction, seal the bottom of the blanks in the filling machine, and then milk from the top opening Filled with juice or other beverage filling and sealed at the top. These packaging materials have the appearance design of the packaging container product printed on the surface thereof.

The web-shaped packaging material is repeatedly and continuously provided with a fold line for one container. Reference is made to FIG. 7 showing a partial packaging material for one container. The web-shaped packaging material with a crease line is composed of a packaging material 27 for one container, a sealing region 28 for vertical sealing, a lateral sealing region 29 for lateral sealing in the transverse direction of the tubular packaging material, a container wall. Panels 25a, 25b, 25c which form a flap 25 which is folded and welded to the side wall or bottom, and the panels 24a, 24b, 24c which form the top wall of the container. A crease line 26 is formed at the border.

In addition to the brick container and gable roof container, there are a single-flow roof container, a triangular prism container, a pentagonal container, a hexagonal cylinder container, and an octagonal container. (See patent literature)
